Somebody in the thread at some point said:
| I'm working on it right now. I noticed what is affecting him. It is
| the 60 milliseconds timeout that we have to avoid jitter. Since the
| ilume keyboard has some inertia it thinks that the user is actually
| pressing the key and that key will take more time to return to its
| normal position.
Ah.
| I tested with 2.6.24 and with 2.6.28 and i see an improvement in
| accuracy in 2.6.28, and 2.6.24 is no better than 2.6.28 in terms of
| timings.
He was comparing it to 2.6.26 which had Tick's patch to improve up /
down tracking but not yet your filter about it, so it makes sense it is
the 60ms thing introduced then.
| I tried a smaller interval (about 15 milliseconds) for the jitter
| problem and things work better. I'll do more tests and send a patch. I
| would like to do what you suggested earlier (faster conversion rate
| for initial events), I am doing tests now.
Great. I don't know increasing the rate will definitely help since it
can be the error early after touch comes from distortion or ripple in
the touch film from the impact or something else that needs some
absolute time to resolve itself. But it does stand a chance as we then
genuinely feed the filter with more information then.
